2020-2025 GM 3.0L Duramax LM2, LZ0 Air-To-Water Intercooler Kit

Duramax LM2, LZ0 Air-To-Water Intercooler Kit Cooler and denser charge air is essential for diesel trucks. It directly impacts performance, efficiency, and engine longevity. That’s why your 3.0L Duramax deserves the PPE air-to-water intercooler upgrade. The PPE intercooler utilizes an all-aluminum, bar-and-plate cooler core with durable cast-aluminum, TIG-welded end tanks. Unlike the factory crimped plastic end tanks, this design offers significantly improved heat resistance and handles turbo boost effortlessly. The PPE intercooler features a 2.4 times larger (140% increase) cooler core and highly efficient cooling fins in both air and coolant passages. The increased core size, combined with fluid-dynamically optimized end tanks, reduces air pressure drop by 77%, resulting in easier and smoother engine breathing and less turbo stress. Our real-world testing showed that the intake air temperatures (IAT) followed the ambient air temperature very closely under various driving conditions.
